1 See the Analog Inputs section.
2 The bandwidth is set with the configuration register
3 LSB means least significant bit. With the 5 V input range, one LSB is 76.3 μV.
4 See the Terminology section. These specifications include full temperature range variation but not the error contribution from the external reference.
5 With VDD = 5 V, unless otherwise noted.
6 All specifications expressed in decibels are referred to a full-scale input FSR and tested with an input signal at 0.5 dB below full scale, unless otherwise specified.
7 This is the output from the internal band gap.
8 The output voltage is internal and present on a dedicated multiplexer input.
9 Unipolar mode: serial 16-bit straight binary.
Bipolar mode: serial 16-bit twos complement.
10 Conversion results available immediately after completed conversion.
11 With all digital inputs forced to VIO or GND as required.
12 During acquisition phase.
13 Contact an Analog Devices, Inc., sales representative for the extended temperature range.
